Wood Avens (Geum urbanum)
A perennial plant in the rose family (Rosaceae), which grows in shady places (such as woodland edges and near hedgerows) in Europe and the Middle East. It is introduced in North America, where it forms natural hybrids with Geum canadense.
Blooms between May and August, and its flowers are 1 – 2 cm in diameter, having five bright yellow petals. The hermaphrodite flowers are scented and pollinated by bees. The fruits have burrs, which are used for dispersal by getting caught in the fur of rabbits and other animals. The roots contain the compound eugenol which is also present in cloves and are used as a spice in soups and also for flavouring ale.
